“…Cystic changes are associated with mucinous degeneration, haemorrhage, necrosis and the formation of microcysts (Fig 5). Kumar et al described two schwannomas that appeared as homogenous, low density masses on CT. 30 They ascribed the low density nature of these schwannomas to their lipid content. In addition, Powers et al described a schwannoma that appeared on CT as a cystic mass but this finding was not explained.…”

“…The mass is rarely calcified, inferior and superior sulci are usually present. [4,8] While bone changes on plain films are generally late manifestations of schwannomas, there are some findings that can help narrow the differential diagnosis. Bone changes, such as erosion of the ribs, may occur as well as neural foraminal enlargement and vertebral body erosion.…”

“…The role of CT in differentiating peripheral nerve sheath tumors is primarily the subject of older studies involving smaller patient populations [48,49]. Neurofibromas can exhibit low density on CT.…”

“…Neurofibromas can exhibit low density on CT. This is due to the presence of lipidrich Schwann cells, transformed adipocytes, accumulation of interstitial fluid and cystic areas resulting from infarctions and necrosis, particularly in cases of larger and malignant nerve sheath tumors [48]. In addition, perineural fat tissue can be entrapped particularly with the growth of diffuse plexiform neurofibromas, thereby causing lower density values on CT [48].…”
